Taxonomic note
"Fragilarie/la is a monotypic genus sometimes, but mistakenly, placed in the Fragilaricaeae or abandoned to incertae sedis, when it is either said to be related to Fragilariopsis Hustedt, as Hendey suggested (1957 [1958], p. 33), or the sole species, Fragilariella dusenii, is a synonym of one or another species in that genus." (Williams 2024: 28). - (06 August 2024) - M.D. Guiry

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
